Intel Core i9-13900K and i5-13600K Review: Raptor Lake Brings More Bite
by Gavin Bonshor on October 20, 2022 9:00 AM ESTCPU Benchmark Performance: Simulation
Simulation and Science have a lot of overlap in the benchmarking world. The benchmarks that fall under Science have a distinct use for the data they output – in our Simulation section, these act more like synthetics but at some level are still trying to simulate a given environment.
In the encrypt/decrypt scenario, how data is transferred and by what mechanism is pertinent to on-the-fly encryption of sensitive data - a process by which more modern devices are leaning to for software security.
We are using DDR5 memory on the Core i9-13900K, the Core i5-13600K, the Ryzen 9 7950X, and Ryzen 5 7600X, as well as Intel's 12th Gen (Alder Lake) processors at the following settings:
- DDR5-5600B CL46 - Intel 13th Gen
- DDR5-5200 CL44 - Ryzen 7000
- DDR5-4800 (B) CL40 - Intel 12th Gen
All other CPUs such as Ryzen 5000 and 3000 were tested at the relevant JEDEC settings as per the processor's individual memory support with DDR4.
Simulation
Outside of the AMD Ryzen 7 5800X3D's dominance in our Factorio testing, the rest of the results paint an interesting picture; the Core i9-13900K excels in simulations. Whether that's the addition of eight more efficiency cores over the Core i9-12900K, or that it's also partly due to increased core clock speeds, if it works, it works. The AMD Ryzen 9 7950X is also a solid contender, however, and it tears the competition a new one in our new John the Ripper MD5 test.

The 7950X outperforms the 13900K from 65W to 185W by substantial amounts: https://www.youtube.com/watch?v=P40gp_DJk5E (19:00, Cinebench R23 multi)It also seems to use less power at lower temps in gaming (23:00, Cyberpunk 2077)
That's probably not the end of the story, but Zen 4 is clearly doing better out of the box. Good news for Dragon Range buyers in 2023. Reply

Very happy that Raptor Lake is super competitive to AMD 7000 series! AMD has to lower it’s high end pricing now for both it’s chipset and retail pricing. Let the price wars begin after Thanksgivings. I expect the 7050X to go from $699 to $499. X670E boards will be the same price as the Intel equivalent models! 😁👍 ReplyDrazick - Thursday, October 20, 2022 - link
Could you build / compiler the SPEC tests with AVX512 flags for the Ryzen 7xxx? ReplyRyan Smith - Thursday, October 20, 2022 - link
It's on the to-do list. Though we're not expecting a significant change in performance. ReplyKangal - Thursday, October 20, 2022 - link
Any plans to test these in thermally or energy-constrained limits? Like with Air Cooling, or certain Watt limits?Or perhaps, how will Zen4 on laptops compare to Intel's RPL-equivalent on laptops...?
From here it looks similar to Zen3 vs Intel 12th, or Zen2 vs Intel 11th. That AMD is competitive in multithread and better efficiency, and Intel only remains competitive by expending alot of power, and it's mostly for the single-core.

Yes. Performance testing at lower power levels is also on the to-do list. We had a chance to play with eco mode a bit for the Ryzen review, but didn't get to do something similar for Raptor Lake. ReplyKangal - Friday, October 21, 2022 - link
Oh nice, will be waiting for that next article to drop. Cheers!Reply

@Ryan: How about testing idle power and realistic day-to-day use cases? I can only find this kind of review for 12th gen vs Zen3 and not 13th gen vs zen4. Would be really nice to have the numbers for 13th zen vs zen4.Here is a link to the review for 12th gen vs zen3: https://youtu.be/4F2z3F64o94 Reply

@Ryan, I am not sure about it.I think enabling AVX512 on Ryzen will have a great effect on the FP tests of SPEC. Reply

There wasn’t a delay when one of the rendering apps got AVX-512 support several years ago. Reply
